楼主我体谅你的心情，下面这是nhibernate中的ReflectHelper的一段源码。
/// <summary>
/// Returns a <see cref="System.Type"/> from an already loaded Assembly or an
/// Assembly that is loaded with a partial name.
/// </summary>
/// <param name="className">The full name of the class.</param>
/// <param name="assemblyName">
/// The name of the assembly. This can be the full assembly name or just the partial name.
/// </param>
/// <returns>
/// The <see cref="System.Type"/> for the class in the assembly or
/// <c>null</c> if a <see cref="System.Type"/> can't be found.
/// </returns>
/// <remarks>
/// Attempts to get a reference to the type from an already loaded assembly. If the
/// Type can be found then the Assembly is loaded using LoadWithPartialName.
/// </remarks>
public static System.Type TypeFromAssembly( string className, string assemblyName )
{
try
{
// try to get the Types from an already loaded assembly
System.Type type = System.Type.GetType( className + ", " + assemblyName );

// if the type is null then the assembly is not loaded.
if( type==null )
{
// use the partial name because we don't know the public key, version, culture-info of
// the assembly on the local machine.
Assembly assembly = Assembly.LoadWithPartialName( assemblyName );
if( assembly!=null )
{
type = assembly.GetType( className );
}
}

return type;
}
catch( Exception e )
{
if( log.IsErrorEnabled )
{
log.Error( className + ", " + assemblyName + " could not be loaded.", e );
}
return null;
}
}

btw：why not open your source？   回复  引用

我想上面的可以得到一个System.Type
那么Activator.CreateInstance(System.Type)就可以得到你要得对象实例。   回复  引用

就觉得奇怪，我怎么没遇到这个问题。我一直都是用LoadFrom，从来没用过LoadFile   回复  引用  查看

Use the LoadFile method to load and examine assemblies that have the same identity, but are located in different paths. Do not use LoadFile to load assemblies that you want to execute.
LoadFile does not load files into the LoadFrom context, and does not resolve dependencies using the load path, as the LoadFrom method does. LoadFile is useful in this limited scenario because LoadFrom cannot be used to load assemblies that have the same identities but different paths; it will load only the first such assembly.   回复  引用  查看

郁闷，去年遇到了这个问题，绕道绕过去了！
今天没有在代码中用到 Assembly ，还有这个问题！！！   回复  引用
